Aly Michalka, who previously starred in Disney Channel's Phil of the Future and currently appears in CBS' Two and a Half Men, revealed that she is engaged to director Stephen Ringer via Instagram Tuesday.

Michalka, who also fronts pop-rock band 78violet with her sister, shared a picture of her huge diamond ring and revealed the proposal took place more than a week ago. "So this happened.....7/8," she wrote.

She also tweeted, "Wanted to share the exciting news! Feel very blessed to know such a great love."

Michalka teased the engagement Tuesday by sharing an Instagram picture of herself posing with her sibling during Just Jared's Summer Fiesta over that weekend. "Hmmm....no one's noticed yet. #Lookcloser," she wrote.

After a commenter figured it out, she replied, "It was literally like right there out in the open hahah."
